Predictions/Expectations/Worries.
I'm worried about Paul Dini not coming back to write the story. I know he said his schedule was full, but I was somewhat hoping they could put off development of a sequel until he could come back, but that probably was hoping for too much. It's that Paul's the only one who can spin a good Batman yarn, far from it, but he is one of the best and I'm concerned that switching writers may lead to some inconsistency. I'm reminded of Mass Effect 3. I'm not talking about the endings, but several key writers had left Bioware during it's development, and you can see numerous plot threads that weren't followed up on, along with some inconsistent characterization. In fairness, Arkham City didn't follow up on several things in Arkham Asylum, so it's really mostly characterization and continuations of certain themes that I'm worried about.
Speaking of themes, my biggest wish for the plot is to explore what Gotham was like after protocol 10, and discuss the question of whether Hugo Strange really did manage to do more for Gotham than Batman has. I don't expect them to say "yes", but with all of the series' talk about saving the city and how Gotham seems to be cursed, I think it should be an important part of the game.
I am a little worried about the new size of Gotham City. It's to be expected, but I fear that expanding the city so much will make navigating a pain in the bat, especially if there are as many Riddler challenges relative to the size of the map as there was in the last game. I do think it's kind of funny that there's apparently going to be five times as many enemies. Gotham had a quarter of it's criminal population slaughtered. Shouldn't there be less enemies?
Not really sure how many villains the game can introduce. They've used all of the well known ones, and some lesser but especially dangerous ones. There are numerous references to Prometheus scattered throughout Asylum and City, which has always made me wonder if they were building up to an appearance. He's pretty obscure, and often poorly handled, but he could provide a unique challenge for Batman.
I'm glad we finally get to drive the Batmobile. That was the only aspect of being Batman the games haven't let us do yet, and with it, the experience will be fully complete.
I want a sequence where you fight alongside Robin and Nightwing against the biggest group of enemies ever encountered in the series. It would be awe inspiring.
In regards to the villains: Killer Croc on Titan. Make it happen.
And I do not want The Joker coming back. No clones, no twins, no resurrection, maybe a hallucination or two, but no real Mc Coy. They have an opportunity that no other Batman series has had, to explore what Batman and Gotham is like after his greatest enemy is gone. I hope to God they don't squander it.
Closing thought: I have to be honest. "Become the Batman" is a pretty lame tagline. Becoming the Batman has been the entire point of the games. Couldn't they have thought of something a little more thoughtful?
